Vascular endothelial cells, a monolayer lining the inner wall of blood vessels, play a crucial role in human health and disease. Abnormal lung vascular endothelial cell apoptosis leads to severe lung diseases, such as emphysema and pulmonary artery hypertension (PAH). The focus of Dr. Lu's study is to understand the regulation of lung endothelial cell apoptosis, particularly by transforming growth factor-beta1 signaling, and its role in the pathogenesis of PAH and cigarette smoke-induced emphysema. The experimental approches include both cultured cells and animal models.

Biography

Research Description

Transforming growth factor (TGF)-beta1, a member of TGF-beta superfamily, is a multifunctional cytokine that regulates numerous cellular functions. Abnormality of TGF-beta1 signaling has been implicated in several lung diseases, such as lung edema, emphysema, and pulmonary artery hypertension (PAH). Using cultured lung macro- and micro-vascular endothelial cells, Dr. Lu will elucidate the molecular mechanism(s) by which TGF-beta1 regulates lung endothelial monolayer permeability, endothelial cell proliferation, and endothelial cell apoptosis. Using animal models of PAH induced by hypoxia and hypoxia plus SU5416, Dr. Lu will investigate the role of TGF-beta1 siganling in the development of PAH. Recently, Dr. Lu has started a new project investigating the role of TGF-beta1 signaling in the pathogenesis of cigarette smoke-induced emphysema, using cigarette smoked animal models. The overall objective of her research is to understand the role of TGF-beta1 in the pathogenesis of these severe lung diseases and hopefully to obtain novel approaches for treatment and prevention these lung diseases.
